autopano-sift-C has an implementation of the SIFT technique, and the 
alternative panomatic implements SURF.  Both algorithms are 
apparently patented, so neither tool could go into Fedora.

This was a problem, so Pablo d'Angelo (the original author of Hugin) 
wrote cpfind, which uses code from panomatic but has an entirely 
novel feature detector.

Yes, the cpfind in Hugin 2011.0.0 is much more reliable than 
autopano-sift-c, but not necessarily faster.  Unfortunately 2011.0.0 
didn't make it into F15, though it will be in F16.
